My area of research involves explicit and implicit memory with a particular focus on explicit recognition judgments; that is, the decision that someone or something was an element of an earlier personal experience. The nature and number of processes involved in recognition memory is currently under debate. Using such methods as 1) statistical modeling of behavioral data, 2) examination of recognition in patients with focal brain damage and 3) functional magnetic resonance imaging (fMRI) of healthy participants during various recognition tasks, we are beginning understand the complex processes which allow us to situate current experiences into our own unique personal pasts.
